Why do you need a hash? An array might be simpler. With a hash, you will need to increment a hash key counter, whearas with an array, you just keep pushing each recv into the array in order received. Anyways, for a hash, something like this would work. There is one glitch, since you are reading a $buf of size 1024, you have no idea where the newlines are going to be, so each hash entry may be an incomplete line, which is continued in the next hash entry. It may be better to concantate all received $buf into one long string, then split the string on newlines at put those lines into a hash. 
use warnings;
use Net::SSH2;

use Data::Dumper;

my $ssh = Net::SSH2->new();

# make a global hash for storage
my %hash;
# make a global counter for incrementing the hash keys
my $counter = 0;
......
......
if($ssh->auth_ok())
{
       runcmd(my_channel($ssh), "$bigcmd");
}

# read output ( but lines may be split )
print $DATA::Dumper( \%hash ),"\n";

__END__

sub runcmd
{
    my ($channel, $command) = @_;
    $channel->exec($command);# or die $@ . $ssh->error();
    my $buff;
    while(!$channel->eof())
    {
        my $buff;
        $channel->read($buff, 1024);
       
        # print $buff;
         $hash{$counter} = $buf;
         $counter++;

    }
    my $rc = $channel->exit_status();
    $channel->close();
    return $rc;
}
